Abstract: The present invention relates to an adhesive sheet which is to be applied to an adherend, in which the adhesive sheet includes an adhesive layer containing a volume change substance that expands in volume upon reception of an external stimulus and thereafter contracts in volume with a lapse of time, and the adhesive sheet is configured so that a plurality of surface irregularities are formed on at least one surface of the adhesive layer as a result of the volume expansion of the volume change substance and that channel areas for air bubble expelling are capable of being formed between said one surface of the adhesive layer and the adherend based on the surface irregularities.
